Restkit 无需请求即可使用对象映射

Question

是使用Restkit框架将json（nsdictionary）映射到对象的任何方法，而无需请求。

我有 JSON，需要在对象中映射它

您可以使用

RKMappingOperation class。这是文档中的示例：

@interface RKMetadataExample : NSObject
@property (nonatomic, copy) NSString *name;
@property (nonatomic, copy) NSURL *URL;
@property (nonatomic, copy) NSDate *mappedAt;
@end
RKMetadataExample *example = [RKMetadataExample new];
NSDictionary *representation = @{ @"name": @"Blake Watters" };
NSDictionary *metadata = @{ @"URL": [NSURL URLWithString:@"http://restkit.org"] };
RKObjectMapping *objectMapping = [RKObjectMapping mappingForClass:[RKMetadataExample class]];
[objectMapping addAttributeMappingsFromDictionary:@{ @"name": @"name", @"@metadata.URL": @"URL" }];
RKMappingOperation *mappingOperation = [[RKMappingOperation alloc] initWithSourceObject:representation destinationObject:example mapping:objectMapping];
mappingOperation.metadata = metadata;
NSError *error = nil;
BOOL success = [mappingOperation execute:&error];
